.WARPING OR BEAMING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 269,400, dated December 19, 1882.

' Application filed July 24, 1882. (No model.)

To all whom zt may concern Be it known that I, THOMAS O.ENTw1s'rLE, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a certain new and usefullmprovement in Warping or Beaming Machines, of which the following is a specification.

My invention relatesto mechanism whereby a greater or less length of yarn, as desired, can be Wound on the warper-beam. Mechanisms for thus determining or measuring the length of yarn are commonly termed clocks or indicators? and obtain their movement from what is termed the measuring-roll of the \varper.

The distinguishing feature of my mechanism resides in an oscillatory nut or carriage, or its equivalent, mounted on a screw which receives a movement of rotation, through suitable intermediariesfirom the measuring-roll,whereby the nut is caused to traverse the screw lengthwise. The nut carries an arm which, while adapted at the proper time to engage the vibrator or rocker or. other appropriate part of the stop-motion, so as to stop the machine, is normally held out of engagement therewithby another arm, (termed, for the sake of distinction, a lifter,) which is also attached to the nut, and operates, in connection with a retaining-bar, to hold the first-named arm (which may be termed the stop-arm) out of engagement with the stop-motion until the nut has traveled a predetermined distance on the screw, at which time the lifter-arm comes opposite a recess, notch, or its equivalent, in the retaining-bar, and thus permits the nut to turn sufficiently to cause its stop-arm to fall into the path of and arrest the vibrator or other appropriate part of the stop-motion. The lilter-arm and retaining-bar are adjustable with relation to one another, so that the lifter-arm may be released from the control of the retaining-bar sooner 'or later in the course of the traversing movement of the nut, according to the length of the yarn to be wound upon the warp-beam.

The nature of my invention and the manner in which the same is or may he carried into effect will be readily understood by reference to the accompanying drawings, in which-- Figure 1 is a diagrammatic representation in side elevation of mechanism embodying my invention. Fig. 2 is an elevation of the nut and parts immediately operating in connection therewith, looking in the direction of the ar row as, Fig. 1.

I have not deemed it necessary to represent the frame and operative parts of the warpingmachine, including the stop-motion. These may be of any ordinary or approved construction.

At a is represented thejournal of the measuring-roll, on which is mounted, as usual, the worm A, which, through the medium of wormwheel B, counter-shaft O, worm D, and the worm-wheel E, rotates the externally screwthreaded hub F, attached to or forming part of the wheel E.

Gr represents the rocking stop-rod, usually termed the*rockerorvibrator, which forms part of the stop-motion, and is similar, for instance, to the rockeror vihratorof the stop-mo tion shown in my Letters Patent No. 257,131 or N 0. 154,466.

That portion of the mechanism in which my invention is more particularly comprised is embraced in the parts lettered H I J K. His a nut or carrier, which is mounted on thescrew F, and is provided with a female screw to engage the external thread on said screw F, the thread making, say, two turns to the inch. From one side of the nut projects the stop-arm I, provided with a notch or shoulder, b, in its outer enlarged end, which is engaged at the proper time by the vibrator G. From the other side of the carriernut projects the litter-arm J, which extends under the horizontal retaininghar K, the latter being so placed that the arm J, when under it, is depressed far enough to lift the stop-arm [above the path of movement 0 v of the vibrator G, as indicated in Fig. 1. The stop-arm l is weighted in this instance by enlarging its outer end, so'that it will hold the other arm, J, firmly up against the under side of the retaining-bar, and it is also made adjustable, so as to be lengthened or shortened, as desired. The retaining-bar K is supported in a bracket, L, which is fastened to some appropriate orconvenient part of the machine-frame, and said bar at its outer end has a notch or re- 10o cess, c, on its under side.

When the machine is in motion the operation is as follows: Movement of rotation is transmitted from the measuring-roll, through the intermediate gearing above described, to the screw F. This causes the carrier-nut H to move lengthwise of the screw, said nut being prevented from following the rotary movement of the screw by reason of the weighted stoparm I, which holds the lifter-arm J up against the retainer-bar K. The arm J, following the movement of the nut, slides along under the retain er-bar until it comes opposite to the notch or recess 0 therein. As soon as it reaches that position the preponderating weightof the stoparm I causes the nut to oscillate or partly rotate to the extent permitted by the depth of the notch or recess a, which will be sufficiently far to permit the. shoulder 11 on the end of the stop-arm I to fallinto the path of movement ofthe vibrator G, with the effect of causing the stop-motion to arrest further movement of the machine in the usual way.

The carrier-nut can be returned to its starting-point with a variety of ways-for instance, by removing one of the gears intermediate between the screw-threaded hub E and the measuring-roll, and then rotating the hub by hand in the direction requisite to bring back the nut; or by making the nut a half-nut, so as to permit it to be readily lifted from and fitted upon the hub; or by the employment of a variety of other expedients within the knowledge of the competent mechanic and requiring no specific mention.

The stoppage of the machine takes place when the lit'terarm is released from the 0011- trol of the retainer-bar to an extent sufficient to allow the stop-arm to drop and intercept the vibrator. This may take place sooner or later in the traverse of the carrier-nut, according to the length of yarn which is to be wound upon the warp-beam, by varying the positions of the retainer-bar and the lifter-arm with respect to one another. Itis'manifest that the said parts can thus be made adjustable in various ways, and I do not desire to be understood as restricting myself to any specific arrangement. That which I have found to be, on the whole, most convenient and best adapted for the purpose consists in mounting the bar K in a socket, d, in bracket L, so that it may slidelengthwise therein, and in providing a set-screw, e,

by means of which said bar can be held fast in any position to which it may be adapted. When a greater number of yards of yarn on the beam is desired the bar K is moved so as to carry its releasing notch or recess 0 farther from the bracket L. When a less number of 'site direction.

capable not only of a traversing movement, but also of oscillating, I can employ a carrier which has only a traversing or longitudinal movement, (imparted to it by any suitable driving-gearing,) and can mount thereon the arms 1 J (which constitute, in effect, the two arms of a lever) in such manner that they may oscillate sufficiently to permit the stop-arm to drop into the path of the vibrator. A spring, instead of a weight, may be employed to hold the lifter-arm against the retainingbar.

The mechanical arrangement of the devices may be further modified and varied in many ways without departure from the principle of. the invention, the essential feature being a stop-arm movable into and out of the path of the vibrator, or other appropriate part of the stop-motion mechanism. combined with detent or retaining mechanism and a carrier or equiv alent movable device, which receives its movement from the measuring-roll or equivalent instrumeutality, and operates at a predetermined point in such movement to effect the release of the stop-arm. from the control of the detent or retaining mechanism.

.What I therefore claim as new and of my in- Vention is as follows:

1. Thecombiuation of the vihratoror rocker, the stop-arm movableinto and out of the patlr of the vibrator, the detent or retaining mechanism, and the carrier, actuated by mechanism substantially as described, and operating ata predetermined point in its movement to effect the release of the stop-arm from the control of the detent or retaining mechanism, the combination being and actingsubstantially as hereinbefore set forth.

2. The combination of the carrier and its actuating mechanism, the oscillatory stop and litter arms, and the retaining-bar, su stantially as and for the purposes hereinbefore set forth.

3. The combination, with the carrier, carrier-actuating mechanism, and stop-arm movable into and out of the path of the stop-motion vibrator or rocker, ot' the llf ItIJ tIID and the retaining-baradjustablerelatively toone another, so as to permit the stop-arm to move into the path ofthe vibrator soonerorlaterin thecourse of movement of thecarrier, substantially as hereinbefore set forth.

4. The carrier-nut and its rotating drivingscrew, in combination with the stop and lifter arms attached to said nut and the adjustable retaining-bar, substantiallyas and for the purposes hereinbefore set forth.

In testimony whereol I have hereunto set my hand this 22d day of July, 1882.
